[0002] To improve the production efficiency of motor rotors, a four-station flying fork winding machine is used to simultaneously wind copper wire around four sets of motor rotors during the motor rotor production process. The technology of the four-station flying fork winding machine is now relatively mature. The four-station flying fork winding machine can automatically feed, wind, and unload motor rotors. However, the traditional four-station flying fork winding machine cannot perform winding work during the feeding and unloading of motor rotors, thus reducing the working efficiency of the device. In view of the above situation, technological innovation is carried out on the basis of the existing large-pitch four-station precision winding machine. Utility Model Content

[0020] Working Principle: The flying fork winding machine is a relatively mature precision mechanical device. Its working principle will not be elaborated upon here. The first servo motor 24 drives the first electrically controlled three-jaw chuck 25 to rotate, thereby causing the motor rotor 26, which is held and fixed by the first electrically controlled three-jaw chuck 25, to rotate. This, in conjunction with the flying fork arm 12, winds the motor rotor 26. While winding the motor rotor 26, the worker can invert another set of motor rotors 26 and insert them into the storage slot of the tray 34. The positioning pin 33 is inserted into the through hole of the tray 34. Combined with the magnetic attraction of the magnetic strip 35 to the iron strip 36, the tray 34 is stably fixed on the top of the lifting plate 31. The electric telescopic rod 3, through the lifting plate 31, can drive the tray 34 upwards, thereby causing the motor rotor 26 in the storage slot of the tray 34 to move upwards and contact the second electrically controlled three-jaw chuck 28. The second electrically controlled... The three-jaw chuck 28 clamps and fixes the motor rotor 26, and then the electric telescopic rod 3 drives the tray 34 to move downward and reset. After the motor rotor 26 clamped and fixed by the first electric three-jaw chuck 25 is wound, the worm gear reducer motor 13 drives the rotating frame 23 to rotate through the rotating shaft 22, so that the positions of the second electric three-jaw chuck 28 and the first electric three-jaw chuck 25 are exchanged. At this time, the flying fork arm 12 can wind the motor rotor 26 clamped by the second electric three-jaw chuck 28. At this time, the electric telescopic rod 3 drives the tray 34 to move upward and approach the second electric three-jaw chuck 28, and then releases the wound motor rotor 26, so that it falls into the storage slot of the tray 34, thereby realizing the continuous winding work of the motor rotor 26. The buffer liner 37 can prevent the wound motor rotor 26 from falling into the storage slot of the tray 34 and causing collisions.
